Linear ACT-31C MegaCode 1-Channel Key Ring Transmitter, Black

For streamlined, reliable access control, the Linear ACT-31C MegaCode 1-Channel Key Ring Transmitter provides secure single-button operation ideal for commercial entrances, gated sites, and managed parking. This Linear key fob transmitter uses MegaCode factory preprogramming (over 1,000,000 unique codes) to virtually eliminate code duplication and strengthen on-site security and monitoring. The compact black housing and quick-disconnect key ring make it convenient for staff and contractors to carry, while two 2016 lithium batteries deliver up to five years of service life to reduce maintenance cycles. The single-channel design pairs easily with Linear receivers and controllers, and a built-in 10-second timeout prevents continuous transmission that could disrupt surveillance or alarm monitoring systems. Lightweight and built for daily use, the ACT-31C integrates seamlessly into access control, alarm, and gate automation setups.
